In Morocco, countries with semi-arid climate, the increasing needs in water for the irrigation, the production of the electricity and the drinkable water supply, required the construction of a large number of dams. This infrastructure has to allow him to earn a living and to proceed to a better management of its resources in superficial waters
The dam BAB LOUTA is situated on the oued BOUSBAÂ (upstream to oued BOUHLOU), near the douar BAB LOUTA of capacity of 35500 million of m3. It has for main function the supply, of the city of Taza, in drinking water. The putting in water of the damis made at the beginning of year 2000. He has to meet the needs for the city. The latter, is situated in approximately 40 km as the crow flies in the southwest of the city of TAZA and 10 km of TAHLA.
This study concerned the physico-chemical quality of waters of the dam and its tributaries. To realize our work, we made, a monthly follow-up, spread out from January, 2016 till December, 2016. Analyses concerned 10 physico-chemical parameters, and 3 bacteriologicals parameters.
